To all'wiwm it mil/y concem:

Be it known that OsWALo H. HANSEN, a citizen of-the United States, residing at. Port Washington, in the county of Ozaukee and State of Vlisc'onsin, has invented a certain new and useful Cooker, of which the following is a specification.

This invention relates in general to provements in the art of treating food stufl's Ml before the same are packed in containers,

and relates more specifically to improvements in the construction and operation of automatic cooking and sterilizing apparatus "for treating corn and the like before the substance is confinedin receptacles such as tin cans.

An object of the invention, is to provide an automatic cooker which is simple in construction and efficient in operation.

Some of the more, specific objects of the invention are as follows:

To provide apparatus which will thoroughly and efficiently heat treat materials with the aid of fluent heating agency.

To provide a cooking device which is automatic and continuous in its operation.

To provide simple, compact and strong cooking mechanism having enormous capacm ity for relatively small space occupied.

To provide a cooker which may be manufactured and sold at relatively low cost, and which is mechanical and neat in appearance.

To provide cooking apparatus all parts of which are convpniently accessible and removable.

To provide a highly sanitary cooker the parts of which may be readily'cleaned, and which is devoid of joints which are subject to leakage.

To provide a mechanically actuated cooker which may he operated and maintained at relatively low cost and with minimum attention.

To provide cooking mechanism adapted vtor direct cooperation with standard filling machines without interfering with the ac:

- cessihility and operation of the can filler parts.

.To provide cooking apparatus which is adapted to deliver treated materials directly to a can filling machine by gravity, thus eliminatin handling of the treated material heiorepacking the same. To provide an improved fluid distr butca I matic cooker, a portion of the cover having been broken away inorder to more clearly disclose internal structure of the device.

Fig. 2 is a fragmentary compound radial section through the improved cooker, part of the section being taken in the radialplane of the discharge mechanism, and another part of the section being taken in the radial plane of the drive mechanism. The improved cooker. illustrated in the drawing comprises generally a stationary frame 2- adapted for direct attachment to the upper portion of a standard can filling achine, a sheetmetal cylindrical tank 3 supported by the lrameQ, a removable sheet metal cover a for thetank'3, a rotaryv steam distributing element orrotor 5 mounted centrally within the tank 3, and mechanism for continuously revolving therotor 5 within the tank 3 during normal operation of the machine. u Q

The stationary frame 2 is provided with projections 18 which serve as a means for attaching the cooker to a can filler frame in'an obviousmanner, and provides a direct support for the bottom 28 of the tank Mounted centrally within the tank 3 and rigidly secured 'within a recess in the tank bottom 28, is a stationary hollow cylindrical'sta-ndard 6, the lower portion oil which is enlarged to form a steam supply chamber 15 and the upper portion of which ispenetrated loy a plurality of transverse steam passages27. Steam'may be supplied directly to the chamber 15 by means of a. pipe, not shown. Within the stationary standard 6, and spaced from the inner surface thereof isa vertical rotary drive shaft 7 the upper portion of which coacts with a hearing at the upper extremity of the standard. 6. The upper end of the rotor sleeve is provided with a transverse slot adapted to receive a transverse driving key 19 which passes through an opening in the vertical drive shaft 7. A collar 21 and hand nut 22 serve to prevent displacement of the rotor 5 relatively to the drive shaft 7. The sleeve of the rotor 5 is provided with a series of radially extending tubular fluid distributing arms, the arms being provided with downwardly directed fluid discharge orifices 9, and the interiors of the arms 8 communicating directly with the annular space between the rotor sleeve and the stationary standard 6.

The lower portion of the vertical drive shaft 7 penetrates the'tank bottom 28 and the stationary frame 2, a stuffing box 16 serving to prevent leakage of fluid at the point of penetration. A bevel gear 14 secured to the lower part of the vertical shaft 7 meshes with a bevel ear 13 secured to an end of the horizontal main drive shaft 10 which is supported in bearings in the stationary frame 2. Thrust collars 29 serve to prevent longitudinal displacement of the drive shaft 10 relatively to the frame. A drive' pulley 11 receiving power from any suitable source, is adapted to be drivinglv connected with the horizontal drive shaft K 10 by means of a jaw clutch 12, operable by means. of a'clutch control lever 24. The

' tion 30 atone side thereof.

jaw clutch 12 is of ordinary construction and comprises a clutch member splined upon the shaft 10 and cooperablewith a second clutch member secured to the,pulley 11 and {Beely rotatable with reference to the shaft .also be provided with other accessories or-' dinarily furnished with this class of apparatus. The cover 4 of the tank 3 is preferably provided with a relatively large opening 23 for admitting the substance to be treated to the interior of the tank .3.

, During normal operation of the cooker,

the clutch 12 is thrown in and rotary motion is being imparted from the pulley 11 to the horizontal shaft 10 and from the horizontal shaft 10 through the bevel gears 13, 14 to the vertical drive shaft 7. R0- tation of the vertical drive shaft 7 is transmitted through the drive key 19 to the rotor 5 causing the tubular arms 8 of the rotor to revolve in horizontal planes within the tank 3. The material to be cooked or sterilized is admitted to the tank 3 through the opening 23 in the cover and after suflicient material has thusbeen admitted, steam underpressure is admitted to the supply chamber 15. From the supply chamber 15 the steam passes upwardly through the interior of the stationary standard 6 and laterally from the interior of the standard 6 through the openings 27 into the interior of the sleeve ofthe rotor 5. The steam thus admitted passes into thevhollow rotating arms 8 from which it is delivered directly into the mass of the material being treated, through the discharge orifices 9. The revolving arms 8 thoroughly agitate the material under treatment and debe opened to deliver the of material may be made continuous by controlling the delivery of material through the valve 17 and by supplying sufficient material to replace that which is being continuously withdrawn. lhe rate of cooking may also be varied by controlling the steam supply and the speed of rotation of the rotor 5. The cookermay thus be operated entirely automatically and continuously to produce an enormous output.

Thesimplicity of the structure from a manufacturers standpoint, is readily apparent and it will be noted that the entire interior of the machine is accessible by merely removing the cover 4. The rotor 5 may be quickly removed by removing the hand nut 22 thereby permitting convenient washing of the'elements to maintain the apparatus in sanitary condition. The stufiing box 16 effectively packs the only joint in the apparatus where leakage might occur thus eliminating all possibility of wasting materials. After being placed in operation, the cooker requires no further attention with the possible exception of manipulation of the steam and discharge control valves in proper treatment of the order to produce material.

It will also be noted that by locating the cooker above and supporting it directly from thecan filling machine, accemibility increase and operation of the flller is not interfered with, and the material may be delivered by ravity directly to the filling machine thereby eliminating handling of t e treated material. It will also be noted that the improved fluid distributing rotor 5 is capable of application to other canning machinery wherein a uniform distribution of steam or other heating a ency is desired It shou d be understood'that it is not desired to limit the present invention tothe exact details of construction and of operation herein shown and described, for various modifications within the scope of the claims may occur to ersons skilled in the art.
